From Zhangye, it is about 12 kilometers along the 312 National Road. The site is divided into the north city of the south city. The south city is mainly built in the Ming Dynasty. It is relatively well preserved. There are residual bricks and ceramics in the city. The walls of the early houses are vaguely visible. The north city was built during the Han to Wei and Jin Dynasties, and because it is close to the Han Dynasty tombs, tombs stealing activities, various sizes and holes in the city can be seen everywhere.
